Compared with other compounds in its class, the molecular weight of 305.10 g/mol gives 7-Bromo-5-fluoro-2,2-dimethyl-2,3-dihydrobenzo[b][1,4]dioxine-6-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
7-Bromo-5-fluoro-2,2-dimethyl-2,3-dihydrobenzo[b][1,4]dioxine-6-carboxylic acid (CAS 2451907-95-0) is a high-purity analytical reference standard with the molecular formula C11H10BrFO4 and a molecular weight of 305.10 g/mol.
The molecular framework of 7-Bromo-5-fluoro-2,2-dimethyl-2,3-dihydrobenzo[b][1,4]dioxine-6-carboxylic acid (C11H10BrFO4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
